USB Debugging option not available


I am currently facing a problem with an Android Tablet, the tablet is working on 2.3.4 and it's a specific tablet (not a usual brand such as Samsung...).

Information on the tablet :

  • Filesystem : Release 4.6.4-r171
  • Kernel : 2.6.35.3-g56a157f
  • It's seems to be a MX 93 (freescale)

I want to connect it for debugging. The problem is there is no "Debugging USB" option to check in the Parameters => Application => Developpment.

Have you any ideas on how to do it ?

Thank you by advance.


Solution

  • To enable ADB manually you need to configure USB interface and start adbd service on the device. First of all install a terminal emulator application. In the terminal run this command:

    setprop sys.usb.config adb
    

    If you are lucky and adbd service is properly pre-configured on your device it should start enumerating now.

    If not - try looking for start adbd in the init*usb.rc files in the / folder. The lines before that command should give you an idea what else could be missing.
